     wherein n, p, R 1 , R 2 , X 1 , X 2 , X 3 , X 4 , X 5 , R 3a , R 3b , R 4 , R 5  and R 6  are as defined in the specification, a process for their preparation, pharmaceutical compositions containing them and their use in therapy.

The present invention relates to compounds having glucocorticosteroid receptor agonist activity, processes for their preparation, pharmaceutical compositions containing them and their therapeutic use, particularly for the treatment of inflammatory and allergic conditions.

Glucocorticosteroids (GCs) that have anti-inflammatory properties are known and are widely used for the treatment of diseases such as inflammatory arthritides (e.g. rheumatoid arthritis, ankylosing spondylitis and psoriatic arthropathy), other rheumatoid diseases such as systemic lupus erythematosis, scleroderma, vascutitides including temporal arteritis and polyarteritis nodosa, inflammatory bowel disease such as Crohns disease and ulcerative colitis, lung diseases such as asthma and chronic obstructive airways disease, as well as many other conditions such as polymyalgia rheumatica. GCs have also been used very extensively for their immunosuppressive properties in the prevention and treatment of transplant rejection. Finally GCs have been used for their anti-tumour effects in a number of malignancies.

GCs act via specific glucocorticoid receptors (GR) that are members of the nuclear receptor superfamily. Ligand binding promotes receptor dimerisation, DNA binding, and transcriptional activation. This mechanism of GC action is well defined in vitro and is critical for regulation of the hypothalamic-pituitary-adrenal axis, gluconeogenesis as well as transcription of anti-inflammatory genes such as mitogen-activated protein kinase phosphatase-1 (MKP-1) and secretory leukocyte protease inhibitor (SLPI) in vivo. Ligand-bound receptor is also able to suppress gene transcription in a dimerisation-independent manner by interfering with the activity of transcription factors, such as AP-1 and NFkB, which are critically involved in the inflammatory reaction.

After ligand binding, the GR translocates from the cytoplasm of the cell to the nucleus and binds to glucocorticoid response elements in regulator regions of target genes. The activated GR then recruits co-factors, including the glucocorticoid receptor interacting protein 1 (GRIP-1) and steroid receptor co-activator 1 (SRC1). These accessory proteins bind to the receptor and link the GR with the general transcription machinery to drive transcription of target genes.

Glucocorticoid effects on transcription may be mediated by both the direct binding of activated GR to target DNA, homodimerisation and recruitment of co-activators (known as “transactivation”) but also by GR interfering with other transcription factor function, including AP-1 and NFkB, by complexing with these other transcription factors and preventing them from binding to their target genes leading to repression of the genes normally upregulated by AP-1 or NFkB (known as “transrepression”). These two modes of receptor activity are dissociable and negative effects on NFkB activity can be retained in the absence of transactivation. It appears that transrepression is largely responsible for mediating the therapeutically desirable anti-inflammatory activity of the GR. Interestingly, the IC₅₀ for inhibition of AP-1 or NFkB (0.04 nM) is lower than the EC₅₀ for activation of target genes (5 nM) and yet high doses of GCs are frequently required to treat patients with inflammatory disease. One explanation is that cytokines expressed at the site of inflammation may induce relative glucocorticoid resistance, for instance by activating AP-1 or NFkB. This is of importance as many pro-inflammatory cytokines signal by activation of NFkB and a major anti-inflammatory action of GCs is thought to be mediated by opposing NFkB action.

Published Japanese Patent Application No. 60067495 describes certain pregnenopyrazoles as anti-inflammatory agents.

There has now been found a new series of glucocorticosteroids having a long duration of action which have potential for once daily administration.

    and pharmaceutically acceptable salts of any one thereof.

It should be noted that each of the chemical compounds listed above represents a particular and independent aspect of the invention.

The present invention further provides a process for the preparation of a compound of formula (I) or a pharmaceutically acceptable salt thereof as defined above which comprises reacting a compound of formula (II)

wherein R^(3a), R^(3b), R⁴, R⁵, and R⁶ are as defined in formula (I), with a compound of formula (III) or an acid addition salt (e.g. hydrochloride salt) thereof

wherein n, p, R¹, R², X¹, X², X³, X⁴ and X⁵ are as defined in formula (I), and optionally thereafter carrying out one or more of the following procedures:

-   -   converting a compound of formula (I) into another compound of         formula (I)     -   removing any protecting groups     -   forming a pharmaceutically acceptable salt.

The above process is conveniently carried out in the presence of an organic solvent such as acetic acid/water mixture at room temperature (20° C.) or, alternatively, in the presence of an organic solvent such as ethanol at a temperature in the range from room temperature (20° C.) to 90° C. Preferably, the reaction is carried out in the presence of a base, e.g. an alkali metal acetate such as potassium acetate.

The compounds of formula (II) may be prepared by reacting a compound of formula (IV)

wherein R^(3a), R^(3b), R⁴, R⁵ and R⁶ are as defined in formula (II), with methyl or ethyl formate in the presence of a base such as sodium hydride, in a manner analogous to the method described in the journal article by Wuest, F et al., Steroids, 68 (2003), 177-191.

Compounds of formulae (III) and (IV) are either commercially available, are well known in the literature or may be prepared easily using known techniques.

It will be appreciated by those skilled in the art that in the processes of the present invention certain functional groups such as hydroxyl or amino groups in the reagents may need to be protected by protecting groups. Thus, the preparation of the compounds of formula (I) may involve, at an appropriate stage, the removal of one or more protecting groups.

The protection and deprotection of functional groups is described in ‘Protective Groups in Organic Chemistry’, edited by J. W. F. McOmie, Plenum Press (1973) and Protective Groups in Organic Synthesis', 3^(rd) edition, T. W. Greene and P. G. M. Wuts, Wiley-Interscience (1999).

The compounds of formula (I) above may be converted to a pharmaceutically acceptable salt thereof, preferably an acid addition salt such as a hydrochloride, hydrobromide, trifluoroacetate, sulphate, phosphate, acetate, fumarate, maleate, tartrate, lactate, citrate, pyruvate, succinate, oxalate, methanesulphonate or p-toluenesulphonate.

The compounds of formula (I) and pharmaceutically acceptable salts thereof may exist in solvated, for example hydrated, as well as unsolvated forms, and the present invention encompasses all such solvated forms.

Compounds of formula (I) are capable of existing in stereoisomeric forms. It will be understood that the invention encompasses the use of all geometric and optical isomers (including atropisomers) of the compounds of formula (I) and mixtures thereof including racemates. The use of tautomers and mixtures thereof also form an aspect of the present invention. Enantiomerically pure forms are particularly desired.

The compounds of formula (I) and their pharmaceutically acceptable salts have activity as pharmaceuticals, in particular as modulators of glucocorticoid receptor activity, and thus may be used in the treatment of:

Thus, the present invention provides a compound of formula (I) or a pharmaceutically acceptable salt thereof as hereinbefore defined for use in therapy.

In a further aspect, the present invention provides the use of a compound of formula (I) or a pharmaceutically acceptable salt thereof as hereinbefore defined in the manufacture of a medicament for use in therapy.

In the context of the present specification, the term “therapy” also includes “prophylaxis” unless there are specific indications to the contrary. The terms “therapeutic” and “therapeutically” should be construed accordingly.

Prophylaxis is expected to be particularly relevant to the treatment of persons who have suffered a previous episode of, or are otherwise considered to be at increased risk of, the disease or condition in question. Persons at risk of developing a particular disease or condition generally include those having a family history of the disease or condition, or those who have been identified by genetic testing or screening to be particularly susceptible to developing the disease or condition.

In particular, the compounds of the invention (including pharmaceutically acceptable salts) may be used in the treatment of asthma {such as bronchial, allergic, intrinsic, extrinsic or dust asthma, particularly chronic or inveterate asthma (for example late asthma or airways hyper-responsiveness)}, chronic obstructive pulmonary disease (COPD) or allergic rhinitis.

The invention also provides a method of treating, or reducing the risk of, an obstructive airways disease or condition (e.g. asthma or COPD) which comprises administering to a patient in need thereof a therapeutically effective amount of a compound of formula (I) or a pharmaceutically acceptable salt thereof as hereinbefore defined.

For the above-mentioned therapeutic uses the dosage administered will, of course, vary with the compound employed, the mode of administration, the treatment desired and the disorder indicated. For example, the daily dosage of the compound of the invention, if inhaled, may be in the range from 0.05 micrograms per kilogram body weight (μg/kg) to 100 micrograms per kilogram body weight (μg/kg). Alternatively, if the compound is administered orally, then the daily dosage of the compound of the invention may be in the range from 0.01 micrograms per kilogram body weight (μg/kg) to 100 milligrams per kilogram body weight (mg/kg).

The compounds of formula (I) and pharmaceutically acceptable salts thereof may be used on their own but will generally be administered in the form of a pharmaceutical composition in which the formula (I) compound/salt (active ingredient) is in association with a pharmaceutically acceptable adjuvant, diluent or carrier. Conventional procedures for the selection and preparation of suitable pharmaceutical formulations are described in, for example, “Pharmaceuticals—The Science of Dosage Form Designs”, M. E. Aulton, Churchill Livingstone, 1988.

Depending on the mode of administration, the pharmaceutical composition will preferably comprise from 0.05 to 99% w (percent by weight), more preferably from 0.05 to 80% w, still more preferably from 0.10 to 70% w, and even more preferably from 0.10 to 50% w, of active ingredient, all percentages by weight being based on total composition.

The present invention also provides a pharmaceutical composition comprising a compound of formula (I) or a pharmaceutically acceptable salt thereof as hereinbefore defined in association with a pharmaceutically acceptable adjuvant, diluent or carrier.

The invention further provides a process for the preparation of a pharmaceutical composition of the invention which comprises mixing a compound of formula (I) or a pharmaceutically acceptable salt thereof as hereinbefore defined with a pharmaceutically acceptable adjuvant, diluent or carrier.

The pharmaceutical compositions may be administered topically (e.g. to the skin or to the lung and/or airways) in the form, e.g., of creams, solutions, suspensions, heptafluoroalkane (HFA) aerosols and dry powder formulations, for example, formulations in the inhaler device known as the Turbuhaler®; or systemically, e.g. by oral administration in the form of tablets, capsules, syrups, powders or granules; or by parenteral administration in the form of a sterile solution, suspension or emulsion for injection (including intravenous, subcutaneous, intramuscular, intravascular or infusion); or by rectal administration in the form of suppositories.

Dry powder formulations and pressurized HFA aerosols of the compounds of the invention (that is, compounds of formula (I) and pharmaceutically acceptable salts thereof) may be administered by oral or nasal inhalation. For inhalation, the compound is desirably finely divided. The finely divided compound preferably has a mass median diameter of less than 10 micrometres (μm), and may be suspended in a propellant mixture with the assistance of a dispersant, such as a C₈-C₂₀ fatty acid or salt thereof, (for example, oleic acid), a bile salt, a phospholipid, an alkyl saccharide, a perfluorinated or polyethoxylated surfactant, or other pharmaceutically acceptable dispersant.

The compounds of the invention may also be administered by means of a dry powder inhaler. The inhaler may be a single or a multi dose inhaler, and may be a breath actuated dry powder inhaler.

One possibility is to mix the finely divided compound of the invention with a carrier substance, for example, a mono-, di- or polysaccharide, a sugar alcohol, or another polyol. Suitable carriers are sugars, for example, lactose, glucose, raffinose, melezitose, lactitol, maltitol, trehalose, sucrose, mannitol; and starch. Alternatively the finely divided compound may be coated by another substance. The powder mixture may also be dispensed into hard gelatine capsules, each containing the desired dose of the active compound.

Another possibility is to process the finely divided powder into spheres which break up during the inhalation procedure. This spheronized powder may be filled into the drug reservoir of a multidose inhaler, for example, that known as the Turbuhaler® in which a dosing unit meters the desired dose which is then inhaled by the patient. With this system the active ingredient, with or without a carrier substance, is delivered to the patient.

For oral administration the compound of the invention may be admixed with an adjuvant or a carrier, for example, lactose, saccharose, sorbitol, mannitol; a starch, for example, potato starch, corn starch or amylopectin; a cellulose derivative; a binder, for example, gelatine or polyvinylpyrrolidone; and/or a lubricant, for example, magnesium stearate, calcium stearate, polyethylene glycol, a wax, paraffin, and the like, and then compressed into tablets. If coated tablets are required, the cores, prepared as described above, may be coated with a concentrated sugar solution which may contain, for example, gum arabic, gelatine, talcum and titanium dioxide. Alternatively, the tablet may be coated with a suitable polymer dissolved in a readily volatile organic solvent.

For the preparation of soft gelatine capsules, the compound of the invention may be admixed with, for example, a vegetable oil or polyethylene glycol. Hard gelatine capsules may contain granules of the compound using either the above-mentioned excipients for tablets. Also liquid or semisolid formulations of the compound of the invention may be filled into hard gelatine capsules.

Liquid preparations for oral application may be in the form of syrups or suspensions, for example, solutions containing the compound of the invention, the balance being sugar and a mixture of ethanol, water, glycerol and propylene glycol. Optionally such liquid preparations may contain colouring agents, flavouring agents, saccharine and/or carboxymethylcellulose as a thickening agent or other excipients known to those skilled in art.

The compounds of the invention (that is, compounds of formula (I) and pharmaceutically acceptable salts thereof) may also be administered in conjunction with other compounds used for the treatment of the above conditions.

The invention therefore further relates to combination therapies wherein a compound of the invention or a pharmaceutical composition or formulation comprising a compound of the invention is administered concurrently or sequentially or as a combined preparation with another therapeutic agent or agents, for the treatment of one or more of the conditions listed.

Human Glucocorticoid Receptor (GR) Assay

The assay is based on a commercial kit from Panvera/Invitrogen (Part number P2893). The assay technology is fluorescence polarization. The kit utilises recombinant human GR (Panvera, Part number P2812), a Fluoromone™ labelled tracer (GS Red, Panvera, Part number P2894) and a Stabilizing Peptide 10× (Panvera, Part number P2815). The GR and Stabilizing Peptide reagents are stored at −70° C. while the GS Red is stored at −20° C. Also included in the kit are 1M DTT (Panvera, Part number P2325, stored at −20° C.) and GR Screening buffer 10× (Panvera, Part number P2814, stored at −70° C. initially but once thawed stored at room temperature). Avoid repeated freeze/thaws for all reagents. The GR Screening buffer 10× comprises 100 mM potassium phosphate, 200 mM sodium molybdate, 1 mM EDTA and 20% DMSO.

Test compounds (1 μL) and controls (1 μL) in 100% DMSO were added to black polystyrene 384-well plates (Greiner low volume black flat-bottom, part number 784076). 0% control was 100% DMSO and 100% control was 10 μM Dexamethasone. Background solution (8 μL; assay buffer 10×, Stabilizing Peptide, DTT and ice cold MQ water) was added to the background wells. GS Red solution (74; assay buffer 10×, Stabilizing Peptide, DTT, GS Red and ice cold water) was added to all wells except background wells. GR solution (7 μL; assay buffer 10×, Stabilizing Peptide, DTT, GR and ice cold water) was added to all wells. The plate was sealed and incubated in a dark at room temperature for 2 hours. The plate was read in an Analyst plate reader (LJL Biosystems/Molecular Devices Corporation) or other similar plate reader capable of recording fluorescence polarization (excitation wavelength 530 nm, emission wavelength 590 nm and a dichroic mirror at 561 nm). The IC₅₀ values were calculated using XLfit model 205 and are shown in Table 1.
